BruCON 2011, day 2 - OpenBeacon RFID Tag Proximity Data was used to build social network graph for second day over all tag IDs in the lounge area (in PDF and PNG format). You can also find the live version of this graph (including source code).

We strongly believe that the future of the Internet of Things can be privacy enabled and can work distributed without selling your soul to large cloud services. Please join our project for enabling that vision!

Introduction

This site collects user and developer documentation for the Open Source and Open Hardware Active 2.4 GHz RFID reader system and our Open Source and Open Hardware active RFID tags.

OpenBeacon Applications

RFID Realtime Tracking System

Location tracking using OpenBeacon tags can be implemented by running a OpenBeacon firmware that regularly
transmits beacon packets. Such packets can then be received by OpenBeacon EasyReaderPoE
base stations in the vicinity. Signals received by one or more base stations can then be used to estimate the position of the tag.
Optional encryption can make sure, that only base stations inside the system can read the packet information.

Indoor Locationing

A compact hardware version of the OpenBeacon USBnode base station is connected to a PDA device or laptop and receives beacon packets from stationary placed beacons. The base station computes its own position in respect to the deployed beacons and transmits this information to the PDA. The PDA can display a map or other location based information to the user.

Social Networking

The SocioPatterns sensing platform employs wearable electronic badges to sense sustained face-to-face proximity between persons –a proxy observable for social contact– with a fine spatial and temporal resolution. It has so far been utilized in fourteen deployments in which the SocioPatterns team was directly involved. Further deployments are being prepared. The platform has additionally been adopted by other research groups and commercial entities which have deployed it and/or are preparing future deployments. Complementing the development of this sensing platform, the SocioPatterns team also works on the development of tools and techniques to facilitate the representation, analysis and visualization of the data obtained from this platform.
